Versuchsvorschrift

To a solution of 5-bromo-6-(2,4,6-trifluorophenyl)-N-[(1S)-2,2,2-trifluoro-1-methylethyl][1,2,4]triazolo[1,5-a]pyrimidin-7-amine (44 mg, 0.1 mmol) and 3-dimethylamino-1-propanol (51 m g, 0.5 mmol) in 1 mL of dimethylsulfoxide at room temperature is added sodium hydride (60% in mineral oil, 20 mg, 0.5 mmol). The mixture is heated at 60° C. for 2 h, and cooled to room temperature. Water is added to quench the reaction, and the product is extracted with ethyl acetate. The organic layer is washed with saturated sodium chloride (x3), dried over magnesium sulfate, and concentrated to a residue. The residue is chromatographed over silica gel, eluting with a gradient of ethyl acetate to 30% methyl alcohol in ethyl acetate. Concentration provides 5-bromo-6-{4-[3-(dimethylamino)propoxy]-2,6-difluorophenyl}-N-[(1S)-2,2,2-trifluoro-1-methylethyl][1,2,4]triazolo[1,5-a]pyrimidin-7-amine as a light tan solid (41 mg, mp 40-42° C.). MS: m/z 523.1, 525.1 (M+H).
